ALFRED P. SCHMUGKER, OF DENVER, COLORADO, ASSIGNOR OF ONE-HALF TOWILLIAM HIOKEY, OF DENVER, COLORADO.

TIME-RECORDER.

To all whom it may concern:

Be it known that I, ALFRED P. SOHMUCKER, a citizen of the United States,residing in the city and county of Denver and State of Colorado, haveinvented certain new and useful Improvements in Time-Recorders; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

My invention relates to improvements in time recorders, my object beingto provide a device which, upon the opening of a door of anestablishment, the time of such opening is automatically recorded. Thisapparatus includes an ordinary clock mechanism having a puncturable dialwhich moves with the hour hand arbor of the clock. Upon this dial areprinted, or otherwise suitably designated, numerals or other charactersto indicate the hours of the day. Upon the framework of the time pieceis mounted a lever having a hook-shaped pointed extremity, its oppositeextremity being connected with one member of a telescoping devicearranged to be actuated by air pressure, the air being ejected from acylinder by the opening of the door, through the instrumentality of aleverlike device, one arm of which is arranged in the path of theopening door. As the hook-shaped lever is actuated, its pointedextremity punctures the time-indieating dial near its periphery, thusleaving a mark to indicate the time of day when the door was opened. Byvirtue of this improvement it becomes practicable for employers to knowaccurately the time of day when an employee enters his place of businesseither in the morning or at any other time when it is desired to keep acheck of this character.

Having briefly outlined my improved construction, as well as the objectit is intended to accomplish, I will proceed to describe the same indetail, reference being made to the accompanying drawing, in which isillustrated an embodiment thereof.

In this drawing, Figure 1 illustrates my improved instrument arranged inoperative relation to be actuated by the opening of a door. Fig. 2 is asection taken on the line Specification of Letters Patent.

Fig. 3 is a section taken on the line 2-3, Fig. 1,showing the parts in a different relative position; that is to say, whenthe device is actuated by the opening of the door. Fig. l is a sectiontaken through the clock mechanism on the line l-4l, Fig. 1, the partsbeing shown on a larger scale. Fig. 5 is a. face view of the clockequipped with my improved device. 6 is a face view in detail of the dialforming a part of the mechanism.

The same reference characters indicate the sameparts in all the views.

Let the numeral 5 designate adoor, and 6 the door frame, the door beinghinged as shown at 7. Mounted upon the top of the frame above the door,is a plate 8. which is secured by screws 9. This plate is provided witha lug 10 with which an air cylinder 12 is pivotally connected, as shownat 13. This cylinder is provided with a piston 14 having a stem 15 whoseouter extremity is pivotally connected, as shown at 16, with a lever 17,fulcrumed at 18 on the outer extremity of a pin 19 with which the plate8 is provided. As shown in the drawing, this pin occupies a horizontalposition and is provided with a leaf spring 20, which bears against thelong arm 21 of the lever 17. The short arm of this lever is providedwith a projection 22, which is pivotally connected with the lever, asshown at 23. Upon this projection is formed a part 2st, which engagesthe edge of the lever and forms a stop to prevent the projection fromturning upon the lever dur ing the opening movement of the door 5, inwhose path the projection lies. During the closing movement of the door,however, this projection turns readily upon its pivot, assuming thedotted line position (see Fig. The inner extremity of the cylinder isprovided with a nipple 25 having an orifice 26 communicating with thecylinder. vl ith this nipple is connected one extremity of a flexibletube 27, whose opposite extremity is connected with a nipple 28, formedon one extremity of a stationary member 29, in which a cooperatingmember telescopes. The nipple 28 is provided with an orifice 31,communicating with a chamber formed by the two members 29 and 30. Thesemembers are normally held in the closed position by a coil spring 32,one extremity of which is connected with the stationary member as shownat while the other extremity is connected with the movable member, asshown at PA. The last named extremity of the spring protrudes from themember 29, as

shown at 35, sufficiently to form a stop, to

limit the inward movement of the member 30, in response to the tensionof the spring.

The telescoping member is provided with a lug 86 with which is pivotallyconnected, shown at 37, one arm of a lever 38 fulcrumed, as shown at 39,on a lug 10, mounted on the top of the time piece d1. The lever 38 isprovided with a slot at), through which the pivotpin 37 passes. The freeextremity of the lever 38 is hookshaped and pointed, as shown at 4:8.

Mounted on the hour hand arbor 4A of the clock movement, is a disk tocomposed of paper or other suitable, readily puncturable material. Uponan inner zone 4E6 of this dial are formed time designations from 1 to 12inclusive, to indicate the hours of the day or night. The area of thedisk is further provided with radial lines at? leading outwardly fromthe Zone 16 and dividing the space of the disk into twelve equalsegments, whose outer portions are sub-divided into four spaces 18. Thisportion of the disk containing the spaces 418, is in position to beacted upon by the pointed extremity 43 of the lever 38 when the latteris actuated for time recording purposes. During this operation the saidlever is thrown to the dotted line position in Fig. 4., by the outwardmovement of the telescoping member 34.

From the foregoing description the use and operation of my improved timerecorder will be readily understood. Assuming that the door is closed,as shown in Figs. 1 and 2, and that the device is arranged, as shown inthe said views, it will be understood that as the door is opened, itsupper extremity will strike the projection 22 of the lever 17. Thisprojection forms a yielding stop, and, as the movement of the door iscontinued, the lever 17 is actuated to cause the piston 1st to enter thecylinder 12, whereby the air is ejected from the cylinder, being driventhrough the orificed nipple 25 into and through the flexible tube 27,whence it passes into the chamber inclosed by the members 2-9 and 30.This air being forced into the chamber of the telescoping members,actuates the movable member 30, whereby the lever 38 is operated tocause its pointed extremity to puncture the time indicating disk in itsouter margin or Zone 48. In order to facilitate this operation, thedisk, which is preferably composed of paper, is supported in the rear bya screw s9 whose nick or groove 50, forms a recess to receive thepointed extremity 43 of the puncturing lever. In order to hold the disk,or dial, in position during the outward movement of the pointedextremity of the lever 38, a small plate 51 is secured to the clockcasing and occupies a position just outside of the dial 4.5. During thepuncturing act the pointed extremity of the lever passes through anorifice in this plate 51, which may be termed the stripping plate. Wereit not for this plate, there would be a tendency for the pointedextremity of the lever to pull the paper dial outwardly with it as thepuncturing extremity of the lever 38 moves away from the dial. Thisplate 51 obviates this difliculty.

The time-indicating dial 45 is readily removable from the arbor etl.Jade fast to this arbor is an auxiliary dial 52, which forms a backingfor the dial to, the latter being held in place by a spring washer whichis secured in place by a. thumb nut 54, screwed upon the threadedextremity 55 of the rotating arbor alt. The disk 53 is provided with atooth or brad 56, which is pressed through the time indicating dial whenthe latter is put in position. This tooth causes the dial containing thetime designations, to maintain its proper position upon the auxiliarydial at all times.

Having thus described my invention what I claim is;

1. In a time recorder, the combination with a door and a time piecehaving a movable dial containing time designations, of a lever fulcrumedadjacent to the time piece, a hollow stationary member, a tubetelescoping in said member, the said tube being connected in operativerelation with the said lever, a spring acting on the telescoping tube tonormally hold the lever away from the said dial, a second leverfulcrumed adjacent to the door and having an arm projecting into thepath of the door when opening the latter, a cylinder also mountedadjacent to the door, a piston therein, a stem connecting the saidpiston with the opposite arm of the second lever, a spring acting on thelast named lever to hold the piston at its outward limit of movement,and a conduit connecting the said cylinder with the hollow member intowhich the said tube telescopes, the arrangement being such that as thedoor acts upon the second lever the telescoping tube is actuated tocause the first named lever to puncture the said dial of the time piece,sub stantially as described.

2. The combination with a door and a time piece having a dial movablymounted thereon and adapted to be punctured, of a lever fulcrumedadjacent to the time piece and having a pointed extremity which, whenthe lever is suitably actuated, will puncture the said dial, a cylindermounted adjacent to the door, a piston therein, a lever connect ed inoperative relation with the piston, the lever having an arm projectinginto the path of the door during the opening moveinent of the latter,and a suitable connection between the cylinder and the puncturing lever,whereby as the door operating lever is actuated, air is forced out ofthe cylinder and serves to operate the puncturing lever, substantiallyas described.

3. The combination with a door, and a time piece, the latter having amovable arbor, of a puncturable dial mounted to turn with the arbor, thesaid dial having time indications and an abutment located in the rear ofthe dial, a perforated plate located in front of the dial, a leverfulcrumed adjacent to the dial and having a pointed extremity which,when the lever is actuated, passes through the opening of the saidplate, punctures the dial and enters a recess formed in the abutment,and a cylinder suitably connected between the door and the said lever,whereby as the door is opened the lever is actuated to puncture thedial, substantially as described.

4. The combination with a door and a time piece, the latter having arotatable arbor, of a dial mounted on the arbor to rotate therewith, thesaid dial having time indications formed thereon, a puncturing leverfulcrumed adjacent to the time piece and arranged when actuated topuncture the said dial, a hollow cylinder, a spring normally holding atube at its inward limit of movement, a second cylinder, a pistontherein, a conduit connecting the two cylinders and means acted on bythe door during its opening movement for actuating the piston, wherebythe air is forced from one cylinder into the other and the telescopingtube operated to actuate the puncturing lever, substantially asdescribed.

In testimony whereof I afliX my signature in presence of two Witnesses.
